Advice on section 2 replacement.

[DropTopKingM3]

Hey guys, I’ll be installing euro headers and euro cats and was looking to replace the resonator in the section 2 with a bigger one. I’m looking to cut down rasp and drone without sacrificing performance. After a lot of research I see it’s best to stay with the stock H pipe section 2.


I see Eisenmann offers a different resonator which is a weld on. I tried researching but haven’t found any info. No measurements or anything.

I was also thinking about a Milltek section 2 which has a “collector”. I’m not sure if that’s the same as the H pipe but the resonator looks bigger than the stock resonator on the oem sec 2.

Here’s a pic of the eisenmann resonator and another pic of the Milltek section 2.

Thanks in advance.

the eisenmann at least looks like it will need some work to install without any flanges. I bet you can find the SS X-pipe available used for cheap from someone looking for the new dual unit.

I have the resonated SS X pipe and I'm happy with the sound. I hated the rasp on my car and got the CPI RTX and SS resonated, it got rid of all the rasp.
